 Let's say I want to self-host my own drawing app.
 
-```bash
-# the app subdomain will be draw.<your-domain>
+First, I'll create a folder for my app:

+```ts
 mkdir -p ~/smallweb/draw

 export default excalidraw;

 And voila! No need to run a single command, your website is already available at `https://draw.<your-domain>`! And each time the drawing is modified, it get automatically persited to `~/smallweb/draw/data/drawing.json`.

 You can invoke:
 
 - the `fetch` function by send a request to `https://example.<your-domain>`
 - the `run` function by running `smallweb run example` or `ssh example@<your-domain>`
+- the `email` function by sending an email to `example!<your-domain>`
 
 Of course, it is super easy to hook these functions to a web framweork like [hono](https://hono.dev) or a cli framework like [commander](https://www.npmjs.com/package/commander).
